Ball valve features and USES

Ball valve features and USES:

V-type regulating ball valve is a core valve seat with metal, or metal teflon seal with the rotary ball valve, it will ball valve and butterfly valve control characteristics combined into one, can be used as a control valve, and can be used as a shutoff valve. Its main features are:

(1) the integral valve body without any pipe joints is not affected by pipe or bolt stress, and the pressure shell is not affected by "sudden change" of pressure because the valve body does not have any pipe joints;

(2) with a v-shaped valve body, even in the case of small flow or high viscosity medium, but also in the whole range, to ensure the accuracy of the control;

(3) leakproof and durable seat lined with stainless steel inner core PTFE cup or O ring at its outer diameter, seat made of tungsten cobalt carbide with a larger cross section, the structure of the seat is further enhanced by an alloy corrugated spring;

(4) when the valve is closed, wedge shear effect will be generated between the v-notch and the seat, which has the function of self-cleaning and can prevent the ball core from sticking, especially suitable for pipe scaling and freezing or containing fiber and particle solids.

Flange ball valves are hard - sealed regulating ball valves. With movable seat structure loaded by plate spring, the seat and the ball will not be stuck or detached. Reliable sealing and long service life. V-shaped cut between the ball core and the metal seat has shear effect, suitable for fiber, small solid particles and slurry and other media. The opening and closing parts adopt v-shaped ball structure, which completely solves the problem that the valve cavity is prone to deposition medium. When the valve is fully open, the flow capacity is large and the pressure loss is small. It has a compact structure and strong universality. The flow characteristic is approximately equal percentage. The adjustable range is large, and the adjustable ratio is 1001. It is used to adjust the pressure and flow of the medium in the pipeline.
